Radio Port Adoption
Figure 2-34. RPs Requiring Layer 3 Adoption
An RP first attempts to be adopted at Layer 2. If Layer 2 adoption fails, the RP
initiates Layer 3 adoption. The RP sends a DHCP request so that it can begin
to communicate at Layer 3.
After receiving an IP address, the RP attempts to contact the Wireless Edge
Services xl Module at Layer 3. The RP can discover the module’s IP address
either through a special DHCP option (option 189) or through Domain Name
System (DNS).
To be adopted at Layer 3, an RP requires:
its own IP address and the IP address of a default gateway
The RP receives both its IP addresses through DHCP. (Because the RP is
on a different subnetwork than the Wireless Edge Services xl Module, the
RP requires the default gateway to route its adoption messages to the
module.)
the IP address of the Wireless Edge Services xl Module
The RP can learn this address in one of two ways:
receiving the address in option 189 of a DHCP configuration
looking up the address through DNS
